4.3.12 (Cont.) TOTALISER MODBUS ADDRESSING
The following table gives addresses for totaliser 1 confi guration data. Generally: Totaliser N parameter
address = totaliser 1 parameter a 162 (N-1) (decimal).
For full details of the Modbus TCP implementation, see
section 8
.
TOTALISER CONFIGURATION DATA
TOTALISER 1
Note: A/B Switching:
B values are not accessible via modbus
for this software version. Span, Zone,
Colour etc. are therefore all setting A
Notes:
1. If an alarm’s Setpoint Source (
section 4.3.3
) is set to anything other than ‘Constant’ the value
returned will be the previously confi gured constant value.
2. If more than 100 Maths channels are confi gured in ‘
Virtual channels
’, then the extra channels
occupy totaliser address space such that maths channel 101 occupies totaliser 1 address and so
on. Totaliser 1 value is to be found at the fi rst address after the fi nal maths channel. Thus, if there
are, for example, 105 maths channels, then Totaliser 1 is found where Totaliser 6 would normally
be. This in turn affects counter addressing as counter addresses immediately follow totaliser ad-
dresses, and in the above example, Counter 1 value would be found at counter 6 address.
